22.2.1 The particulates, water immersion or spray, and frequency of occurrence shall be
defined for normal and abnormal operating conditions.
22.2.2 The submarine, systems, equipment and components that are required to operate within
a particulate laden, water spray or water immersion environment in normal and
abnormal operating conditions are to be identified. They shall be able to operate
with defined levels of particulates, water or immersion or be fitted with suitable
protection measures.
22.2.3 The submarine, systems, equipment and components that are required to survive and or
operate after exposure to a particle laden, water spray or water immersion
environment in normal and abnormal operating conditions are to be identified. They
shall be able to operate after being exposed to particulates, water spray or water
immersion environment or be fitted with suitable protection measures.
22.2.4 The submarine, systems, equipment and components that are required to operate within
a water immersion environment in emergency operating conditions are to be
identified. They shall be able to operate with defined levels of immersion and
external pressure, e.g. life support systems for abandonment and rescue.
22.2.5 The potential for the submarine, systems, equipment and components to release
particulates or water spray shall be defined for emergency operating conditions. The
following accident scenarios shall be considered: smoke, dust, fire residues,
abrasion of rotating equipment, leakage of submarine systems, leakage of
penetrations.
22.2.6 The submarine, systems, equipment and components that are required to
operate within a particulate laden environment in emergency operating conditions are
to be identified. They shall be able to operate with defined levels of particulates.
The smoke environment is defined in Vol 1, Pt 4, Ch 4 Materials.
22.2.7 Generation of particulates shall take account of the impact on embarked
persons.
